GE DS200SHCBG1ABC Shunt Connector Board

الوصف

The GE DS200SHCBG1ABC is a specific revision of the Shunt Connector Board (SHCB) used in the GE DS200 Drive Series and Mark V Speedtronic Turbine Control Systems.¹

Its function is passive and crucial for accurate current measurement; it acts solely as a highly reliable interface and termination point for routing the low-voltage signals from the current shunts.

Core Function and Purpose

The SHCBG1ABC is a non-processing component, dedicated to signal integrity within the high-power drive cabinet.

1. Shunt Signal Termination: High-power DC circuits use current shunts to measure large currents (Armature or Field) by sensing the tiny, proportional voltage drop (typically in the ²$\pm 50 \text{ mV}$ to ³$\pm 100 \text{ mV}$ range).⁴ The DS200SHCBG1ABC provides the secure, robust connectors necessary to terminate the delicate wiring carrying these signals.

    

2. Signal Routing: It acts as the intermediary, cleanly routing the low-voltage shunt signal to the main Instrumentation Board (like the SDCI or DCFB). This instrumentation board performs the critical tasks of isolating, amplifying, and converting the analog signal into a reliable digital format for the main drive controller (SDCC).
3. Specific Configuration: The SHCB designation (as opposed to SHCA) often indicates a physical or current range specification. This board is typically designed for a specific set of shunts or current ratings, such as those associated with up to approximately $65 \text{ A}$ circuits, ensuring the correct level of signal fidelity is maintained for that range.
